WINDMILL.

SPECIFICATION forming part of Letters Patent No. 250,661, dated December13, 1881.

Application filed September 14,1881. (No model.)

To all whom it may concern:

Be it known thatl, CLARENCE J. HAMILTON, of Plymouth, in the county ofWayne and State of Michigan, have invented an Improvement in Windmills,of which the following is a specification.

Thenature of this invention relates to certain new and usefulimprovements in the construction of windmills; and the inventionconsists, first, in the peculiar construction and arrangement of parts,whereby the sails of the wind-wheel are automatically presented to theaction of the wind; second, in the peculiar construction and arrangementof parts for throwing the sails out of the wind; and, third, in thepeculiar construction, arrangement, and various combinations of theparts, all as more fully hereinafter set forth.

Figure 1 is a perspective view. Fig.2 is an elevation of the automaticgovernor and connections therewith. Fig. 3 is a detailed perspective ofgovernor-connections for throwing in and out of wind.

In the accompanying drawings, which form 2 5 a part of thisspecification, A represents a'suitable turn-table, which is mounted upona hollow stand-rod, B, which, in turn, is supported by any suitableframe-work. In this turn-table A is journaled the shaft O, in properbearings;

0 and to the outer end of such shaft is rigidly secured the hub D of thewind-wheel E. To

this wheel E are rigidly secured the inner ends of the arms F, whichradiate in lines tangential from the periphery of the hub D, and these 35 arms are further secured at theproper distances apart by means of theband G, to which they are rigidly attached. To the outer portions ofthese arms are pivotally secured the sails H h h, which are of the classusually denominated 4o double-winged sails, the smaller ones, h, of

which are connected together pivotally by the rods a.

Properly journaled upon the shaft (Land between the hub D and the end ofthe turn-table,

5 is an elongated plate, I, to each end of which is rigidly secured abar, J, the outer end of each of which is connected by means of alink orrod, 1), to the smaller portion, h, of one of the sails, H, as isclearly shown in Fig.2. Each of these bars J has pivoted to or near itsouter 5o endalever, K, the outer or longer arm of which is provided withan adjustable weight, L, while the shorter arm is connected by means ofa link, 0, to one of the arms F, the parts being arranged andconstructed as is clearly shown in the drawings. The rear end of theshaft 0 is connected by any proper means to the pumprod in such a manneras to impart a reciprocating motion to the same.

Upon opposite sides of the plate I, andnear the ends thereof, arepivotally secured the bellcrank levers M, the shorter arms of whichimpinge against pins 0, Fig. 3, which are secured to the wind-wheel E;or such arms may impinge against one of the spokes of the windwheelwhere the construction of the wheel will admit of it. The longer arms ofthese bellcrank levers M impinge against the face of the annular ring N,which is capable of having a horizontal movement upon the turn-table,and by which it is guided, said ring being secured to a frame, 0. It isguided in its movements by the turn-table, which is connected by meansof bars P to the yoke R, which, in turn, is rigidly secured to the leverS, which is fulcrumed between projectionsT from the turn-table. Acoil-spring, h, is secured at one end to the short arm of this lever S,while its opposite end is secured at any suitable pointupon the table,and is for the purpose of retaining the annular ringNin its retractedposition, as hereinafter described, while the lever S has secured to itslonger arm a rod or cable, U, which extends down to within easy reachfrom the ground, andby means of which the annular ring may be projectedfor the purposes herein after explained.

'In practice, when the wind is blowing at a moderate force it strikesthe sails H upon the side,usuall y near the rear face of the wheel, andcauses the wheel to revolve, and imparts a reciprocating motion to thepumprod. As the wind increases in force and the wheel has a tendency torevolve with a greater velocity, the weights L will, by centrifugalforce,be compolled to assume a linewith the bars J, and therefore mustnecessarily, by the connectingrods hereinbefore named, draw the sailsand turn them so that their edges will be presented to the wind, theaction of these weights and their connections upon the sails causingthem to present a lesser area of their surface to the action of the windas the latter increases in force. As the wind decreases again the partsassume their normal condition, and are assisted in this action by thecoil-springs 71. hen it is desired to throw the sails entirely out ofthe wind and retain them in that position, the annular ring N isprojected by pulling down upon the cord U, causing the said ring topress against the longer arms of the levers M,which,

their shorterarms finding resistance upon the pins'e, causes the plate Iand its connections to move radially, and thus draw the sails so thattheir edges will be presented to the action of the wind.

What I claim as my invention is 1. In a windmill, the sails H,consisting of wide wings h and narrow wings h, secured to opposite sidesof the arms F, in combination with the weights L and connections,substantially as described, between the weights and sails, whereby thecentrifugal action of the weights when the wheel is turning will causethem to move toward the circumference of the wheel to regulate thepositions of the'sails, as set forth.

2. In a windmill, and in combination with the plate I and itsconnections, substantially as described, the horizontal moving ring Nand frame 0, secured to the yoke R by means of the bars 1?, said yokebeing secured to a lever,

S, as described, and by means of which the said ring and its frame areprojected or retracted for the purpose of operating the lever M,fulcrumed on the plate I, substantially as and for the purposes setforth.

3. In a windmill, the pivoted sails H, provided with wings h h, ofunequal area, and connected by rods to, in combination with the plate I,rods J, weights L, weight-levers K, rods 1) 0, and the springs i,substantially as and for the purpose specified.

4. In a windmill, the pivoted sails H h h, plate I, rods J, weights L,weight-levers K, rods 1) c, and springs i, in combination with the leverM, the horizontally-sliding ring N, frame 0, rods P, yoke It, lever S,spring h, and cord U, substantially as described, and for the purposespecified.
